Virgin Atlantic said they are "deeply concerned" by reports that eight celebrities flight details may have been passed on to a paparazzi agency by a former employee.

The allegations that have been raised are extremely serious and we have launched an immediate investigation.

The security of customer information is our highest priority and we have robust processes in place to ensure that passenger information is protected. The incident that has been alleged concerns eight customers’ flights booked in 2010 and we are in contact with all of those people.

It is too early to draw conclusions on this matter but of course we would deeply regret any concern that these allegations may cause the individuals involved.”
